Application filed July 23,

To all whom it may concern:

Be it known that I, EDGAR G. McCor- L'o'UGH, a citizen of the United States, residing at Winston-Salem, in the county of Forsyth and State of North Carolina, have invented certain new and useful Improvements in a Flue Shutter, of which the following is a specification.

This invention relates to attachments for chimneys or fines for smoke pipes and the primary object of the invention is to provide novel means for closing flue openings in walls when a stove is not connected with the chimney, the said means acting as a fire protector to the walls of the chimney.

Another prime object of'the invention is to provide an improved attachment for flue openingembodying a casing arranged to be fitted in the wallcontaining the flue opening, and shutter-plates carried by the easing for permitting the closing of the openings when desired, the attachment presenting an attractive appearance, when the stove is taken down for any cause, the shutter plates effectively hiding the opening in the Wall.

A still further object of the invention is to provide animproved device of the above character, which will be durable and efficient in use, one that will be simple and easy to manufacture, and one which can be placed upon the market at a small cost.

With these and other objects in view, the invention consists in, the novel construction, arrangement and formation of parts, as will be hereinafter more specifically de scribed, claimed and illustrated in the accompanying drawings, in which drawings:

Figure 1 is a perspective view of the improved attachment showing the same in position with the shutter plates thereof closed, for hiding the flue opening in the wall.

Figure 2 is an enlarged front elevation of the improved attachment with the cover plate removed and showing the shutter plates in their open position.

Figure 3 is a similar View showing the shutter plates in their closed position for covering the flue opening in the wall,

Figure 4: is a detail perspective view of the various parts of the shutter, and

Figure 5 is a detail sectional view taken on the line 5-5 of Figure 3, illustrating the formation of the casing of the attachment.

Referring to the drawings in detail, wherein similar reference characters desig- 1923. Serial No. 653,333.

nate corresponding parts throughout the several views, the letter 11 generally indicates the improved attachment andB a wall or chimney provided with a fine opening.

The improved attachment A comprises a casing or housing 10, which is adapted to be countersunk in the wall or chimney about the flue opening. This housing 10 includes a rear wall 11 having the outwardly extending right angularly disposed side walls 12 The side walls 12 are provided with attaching flanges 13, to which is adapted to be bolted or otherwise secured the cover plate 14. As clearly shown in Figures 1 and 2 of the drawings the rear wall 11 and the cover plate 14; are provided with aligned openings 15 which are adapted to register with the smoke pipe or flue opening in the wall or chimney B. If desired a thinible 11 can surround the opening-15 in the cover plate to facilitate the attaching of a smoke pipe of a stove thereto.

Arranged at equidistant spaced points, on each side of the opening 15' in the rear wall 11 is a pair of double ended operating levers 16 and 17, which are arranged in parallel relation to one another and normally disposed in a vertical position. These double ended levers 16 and 17 are pivota-lly mounted at a point equidistant their ends upon suitable pivot pins 18 carried by the rear wall 11. The terminals of the levers are connected by upper and lower links 19 and 20 by means of suitable pivot pins or the like 21. The shutter plates 22 and 23 provided for closing the flue openings are dis posed between the rear wall 11 and the links 19 and 20 directly in' the casing. These shutter plates are of a flat rectangular shape and can be formed of cast iron if so desired. As clearly shown in Figures 2 and 3 the shutter plate 23 is rigidly connected at its lower end, by suitable rivets or the like 24.: to the link 20 at one sideof the transverse center thereof. The shutter plate 22 is rigidly connected by means of rivetsor-the like 25 to the upper link 19 at one side of its transverse center and it is obvious that when the operating lever-s 16 and 17 are rocked upon their pivots, that the shutter 7 plates 22 and 23 will be moved toward and away from the flue opening according to the direction of movement of the levers. In order to facilitate the operation of the flue plates, the flue plate 23 is provided with a depending arm 27 and this arm carries an outwardly extending operating handle 28, which is extended through a suitable slot 29 formed in the cover plate 14.

In use of the improved attachment, when the stove is taken down, the handle 28 is moved in a counterclockwise direction, which will effectively move the shutter plates 22 and 23 over the flue opening, thus efleotively hiding the same from view from the casual observer.

Now when the stove is set up for the winter it is merely necessary to connect the stove pipe with the opening 15 in the cover plate 14 and then move the handle 28 in a clockwise direction, which will move the shutter plates 22 and 23 away from each other and thus permit the passage of the smoke and products oi combustion into the flue or chimney.

From the foregoing description, it can 'be seen that l have provided an exceptionally simple and durable device for connection with flues, which will effectively hide the flue opening, when the stove is disconnected from the flue for any reason.

Changes in details may he made without departing from the spirit or the scope of this invention.

What I claim as new is:

1. An attachment for flue openings CO1'I1 prising a casing having a flue opening therethrough, a pair of sliding shutter plates arranged in the casing for movement across the flue opening, a pair of parallel doubleended levers pivotally secured at a point equidistant their ends in the casing in spaced relation to the outer ends of the shutter plates, parallel disposed links connecting the terminals of the levers together, means attaching one flue shutter plate to one link and means attaching the other flue shutter plate to the other link.

2. An attachment for flue openings, comprising a casing including a rear wall, side walls, outwardly extending attaching flanges formed on the side walls, a cover plate connected with the flanges, the cover plate and rear wall having aligned flue openings therein, a pair of double ended operating levers pivoted at a point equidistant their ends for swinging'movement in the casing, links connecting the upper and lower ends of the pair of levers together, shutter plates disposed in the casing, means securing the lower end of one shutter plate to one link, means rigidly securing the upper end of the other shutter plate to the other link, and an operating handle formed on. one shutter plate and extending through the cover plate.

In testimony whereof I aflix my signature in presence of two witnesses.
